This tincture was doubled in strength in the U. S. P. VIII. The British tincture (1914) is half the strength of the U. S. P. tincture.
The tincture of tolu has the properties of the balsam, and may be employed as an addition to expectorant mixtures in chronic bronchitis, but the proportion of alcohol is too large to allow of its advantageous use in some cases. It is used in preparing the syrup of tolu. In smaller quantities it is often employed to flavor cough mixtures. It is precipitated by aqueous liquids.
Dose, one-half to two fluidrachms (1.8-7.5 mils).
